Texas Instruments UCC3805NG4 is an 8-PDIP packaged DC-DC controller IC designed for multi-topology operation. This component supports Buck, Boost, Flyback, and Forward converter topologies, enabling step-up, step-down, and step-up/step-down voltage conversion. Featuring frequency control, the UCC3805NG4 operates at a switching frequency of 31kHz with a maximum duty cycle of 49%. It is configured for a single positive output and utilizes a transistor driver for the output stage. The IC requires a supply voltage (Vcc/Vdd) ranging from 3.6V to 12V and operates within an ambient temperature range of 0°C to 70°C. Its through-hole mounting type facilitates integration into various circuit designs. This controller finds application in power supply units and power management systems across multiple industries.
